Embodiment 1

[0032] (1) Preparation of Acetobacter agent, take a ring of Acetobacterfabarum (Acetobacterfabarum, preservation number CICC No. 10883) from the inclined surface of the test tube, inoculate it into 30-100mL sterilized acetic acid bacteria medium, and incubate at 30-32 ℃, 100-125r·min -1 Cultivate on a shaker for 22-26h, then insert it into 0.6-0.8L sterilized acetic acid bacteria culture medium, at 30-32°C, 100-125r min -1 Cultivate on a shaker for 22-26 hours, and make a seed solution of the bacteria for use. At this time, the number of viable bacteria in the solution is ≥108CFU·mL -1 .

[0033] Acetobacter lovaniensis (Acetobacter lovaniensis, preservation number is ATCC No.12875) is cultivated corresponding strain seed liquid with reference to above-mentioned culture method;

[0034] Two kinds of Acetobacter are formulated into Acetobacter agent in a ratio of 1:1;

[0035] The above-mentioned acetic acid bacteria culture medium is, glucose 98g L -1 , yeast extract 9g·L ...

Embodiment 2

[0045] See Example 1 for the configuration of the seed liquid of each bacterial strain in the EM bacterial agent in this embodiment, the difference is that the ratio of each raw material is different, and the preparation method is the same;

[0046] This embodiment provides a kind of micro-ecological preparation for the purification of aquaculture tail water, which is prepared from the following raw materials in parts by weight: 60 parts of EM bacterial agent, 80 parts of nutrient agent;

[0047] Wherein, the EM bacterial agent is composed of the following bacterial agents in parts by weight: 40 parts of Acetobacter agent, 15 parts of Bacillus agent, and 10 parts of nitrifying bacteria agent;

[0048] The nutritional agent is prepared from the following raw materials in parts by weight: 10 parts of glucose, 3 parts of brown sugar and 3 parts of soybean meal.

[0049] The preparation method is to mix the seed liquids of each bacterial agent in the above ratio to make EM microbi...

Embodiment 3

[0051] See Example 1 for the configuration of the seed liquid of each bacterial strain in the EM bacterial agent in this embodiment, the difference is that the ratio of each raw material is different, and the preparation method is the same;

[0052] This example provides a microecological preparation for the purification of aquaculture tail water, which is prepared from the following raw materials in parts by weight: 80 parts of EM bacterial agent, 100 parts of nutritional agent;

[0053] Wherein, the EM microbial agent is composed of the following bacterial agents in parts by weight: 40 parts of Acetobacter agent, 15 parts of Bacillus agent, and 20 parts of nitrifying bacteria agent;

[0054] The nutrient is prepared from the following raw materials in parts by weight: 15 parts of glucose, 5 parts of brown sugar and 5 parts of soybean meal.

[0055] The preparation method is to mix the seed liquids of each bacterial agent in the above ratio to make EM microbial agent, and the...

Abstract

The invention discloses a microecological preparation for purifying aquaculture tail water, and relates to the technical field of biological preparations. The compound microbial agent is prepared from the following raw materials in parts by weight: 50-80 parts of an EM microbial agent and 50-100 parts of a nutritional agent, wherein the EM microbial agent is prepared from the following microbial agents in parts by weight: 40 to 50 parts of an acetobacter aceti agent, 10 to 15 parts of a bacillus agent and 10 to 20 parts of a nitrifying bacteria agent; the microecological preparation provided by the invention is safe and environment-friendly, can reduce organic matters in aquaculture water, greatly reduce the content of ammonia nitrogen, nitrite and hydrogen sulfide and chemical oxygen consumption of sludge at the bottom of a pond, effectively improves the water environment of aquaculture tail water on the premise of considering the preparation cost, can be recycled, and is beneficial to environmental protection. The material circulation in the water body is promoted.

Description

technical field [0001] The present application relates to the technical field of biological preparations, in particular to a microecological preparation for purification of aquaculture tail water and a preparation method thereof. Background technique [0002] In recent years, the aquaculture industry has developed rapidly, and the scale of intensive high-density breeding has continued to expand, which has promoted the development of the social economy to a certain extent. damage, and greatly increased the chance of cross-infection of pathogens among aquatic animals. For this reason, various fish diseases frequently occur, and even cause large-scale death of aquatic animals, and the environment of aquaculture water body also deteriorates thereupon. For the prevention and treatment of fish diseases, the traditional method is mainly to use antibiotics and some chemically synthesized drugs as feed additives or fish medicines in large quantities. The long-term use of antibiotic...
